Tunneling in partial coherence through a series of barriers: an explicit result from a pure dephasing model
arXiv:cond-mat/0106439 · doi:10.1103/PhysRevB.65.155326
Abstract
Within the Büttiker dephasing model, the backscattering in the dephasing process is eliminated by setting a proper boundary condition. Explicit expression is carried out for the effective total tunneling probability in the presence of multiple pure dephasing scatterers with partial coherence. The derived formula is illustrated analytically by various limiting cases, and numerically for its application in tunneling through multi-barrier systems.
